Spring hinge and adjustable leaf



Aug. 29, 1933. E. BOMMER spams HINGE AND ADJUSTABLE LEAF Filed A ril '28, 1932 INVENTOR- BY O Patented Aug. 29, 1933 i This invention relates to single and doubleact ing spring hinges, andrnoreparticularly to-im provements in spring hinges of the so-called' clamp-flanged typewhich are used more especial-- I ,6 1y for hanging doors' to marble, slate or stone par-- titions or stiles-and for similar purposes.

The inventionhas for its object and purpose to provide a simple, practical-and efficient leaf of the so-called clamp-flanged type foraccommodating the partition or stile, and, to provide in this regard a construction having novel features] of adjustabilityby means of which the stile may be snugly and firmly embraced without the neces sity of cutting, chipping, mortisirig or otherwise preparing the stile for the application ofthe hinge thereto. e i

In carrying my improvements into effect; the flange adiacent the hingebarrel is mounted for relative adjustment withj'res'pect to the other of the flanges and with respect to the leaf web,

the adjustable connection for this purpose being provided directly between the leaf web and the adjustable flange and consisting in the example herein given-of projections on the leaf web which engage between longitudinal guide walls extending transversely of the adjustable flange. For i the, production of the longitudinal guidewalls, the adjustable flange is expandedv adjacent the leaf-web, the expansion'bei'ng on the outside and toward the hinge barrel to provide an outside apron behind which the adjustable connection is concealed irrespective 'of theadjustment of the adjustable flange.

- Another object andpurpose' of-my invention is' to provide an adjustable flange which is adjust ablein two directions first,- along theweb toward and away from the stationary flange, and sec-'- ondly, in a plane at right angles or substantial p'ensate for any malformation inthe angularity of the sides of the stile with respect to the inner edge thereof and at the same time topro'vide for accurate; alignment of the ,bolt receiving holes in the adjustable flange 1 with the bolt-receiving holes of the stationary flange.

With the foregoing and other objects in view,

the invention consists of the novel construction, combination and arrangement of'parts as here inafter more specifically described with reference the hinge barrel is a'hinge] pin 14 anda {'co'ile'd I I f Opposing the flange ly at rightangles to the web in order to comf ent invention, parts being brokenawayqandjthe I hingeleaves being shown in open or .spre'a'd relation;f c: Fig. 2 is a cross sectional view onitheline 2 2.

the spring hinge. in'which I have illustrated a simple andfpractical example of my improve Iments as reduced-to practice, comprises a. door leaf 10,-'a" stile leaf or web 11 andahinge barrel 12, the door leaf '10 and binge barrel 12 being madeintegralan'd the-leaf or web 11 having in-' tegral lugs or ears 13 which are located at opposite ends of the hinge barrel. Arranged within 8 tensioning spring 15; and disposedbetween the upper end of-the hinge barrel 12 and the toprear, or lugfil3'isa tensioning-eollar-16 by"means or which to" tension the spring in a manner wellf Known in the art. All of these parts maybe of any 'well-known'or approved construction. I The stile leaf or web 11 is made with a-la terally projecting flange 17 in a plane substantially at right -angles'to the plane of' theweb 11,- This flange extends along the outer. edge of 'the web and will be hereinafter referredito as the stationary or fixedflange. Q1 17 1'7. on the sar'neside of the web 11 is a flange lfl which will be hereinafter referred to-as the adjustable flange. ,The web 11 together with the stationary flange 17' end-ad:

justable flange 18 forms .the so-called' clamp-e. flanged-type of laf-in' which received the edge 7 portion-19of the stile or other element which isto be'secured to and-between the two flanges. The construction of means by which Iv pro- 'vide,;in'accordance' with'the present invention; 'for the adjustment of the flange 18 consists in forming the web 11 adjacent thehinge'ba'rrel with projections or.studs 20 and 21." For'receiving'the. projections or studs 20 and 21', the innerv edge 22 ofthe flange- 18 "is; provided with longitudinalqx recesses 23 and 24, respectively; the recessj23;be ing defined by longitudinally" extending; guide walls 23%- 23', while the recess 24a formed b and the apron extension isso. spaced from the plane ofthe inner edge22lthatthe recesses will walls extend transversely of the flange-18, so that when the recesses have been applied to the studs the flange 18 can be adjusted alongthe web 11 toward or away fromrthe opposite flange 17, in orderto accommodate the thickness of the stile portion 19.

It will be noted that the studs 20 ,and'21 -do v not project at right angles from the .weblL but are inclined from the perpendicular} the two studs in the present embodiment inclining or sloping toward each other so that the distance between their outer ends will be less than the distance between their base. portions. For slidably accommodating the studs, theirecesses in the flange 18 and hence the guide walls defining thef recesses are appropriately inclined from the" perpendicular; the two pairs of walls 23', j23'g'and; 24 24' inclining in opposite-directions. For-the production of the transversely extend- 'inglguide walls, the flange'llislformed at its inner end 22 with an apron extension 25 which projects toward the hinge :b'arrel. This apron extension is not even with theinn'er edge22' of the flange, but is set back from the plane thereof and constitutes the baseifor thetransversely' extending guide walls. Accordingt'to thisform of, construction, the free edges of the guide walls are even with the inner edgeg22ofthe flange,

be of agreater depth than the lengthof the. studs,

as clearly shown in Fig.5. By reason of this arrangement, 'the flange 18'is not only adjustable toward and away from the stationary flange. 1'7,

but also has alde greeof adjustment toward and of the stationary flan Whfl atthe Same time away, from the web, so thatthe bolt-receiving I eyes 26 of the flange 18 can be brought into precise alignment with the bolt-receiving eyes 27 compensating for any malformation in the angularity of the faces 28, 28" of the stile with respect' to, the outeredge 28' thereof which abuts against-theweb ll. Notwithstanding the inclination of the studs, the adjustable hinge is readily applied thereto by'disposing theinner edge 22 of the flange in closeproximity to the barrel and then-- applying the recesses to the studs by giving the, flange a turning action until ,the flange 1 as-- sumes a position substantially atrig'ht angles to the web, The apron extension 25 not only serves as abase for the transversely extending guide walls but also'serves as means for concealingthe adjustable connections-between the {web and, flange irrespective of the position of adjustment of the flange. 1

- The adjustable flange of my invention is simple in construction and economical in manufacture, and while possessing the, advantage of being adjustable in one direction to accommodate the v thickness of the stile an'din another direction to compensate for; any, malformation. in the sides I of the stile, it has the further advantage, because of the apron extension, of concealing the adjustable connections, irrespective ofthe relative adjustment of the flange' While my invention has been illustrated and described in particular in connection with the stile leaf, it will be obvious that itmay be produced; in connection with the door leaf. or also that' itmay be produced in connection with an adjustablejleaf for a door strike; or similar device.

my improvements as reduced to practice, it will be recognized that the disclosure given is an example only, and .is susceptible to more or less modifications in the form, proportions and relative arrangement of the various parts, and I,,
